Infrared Patching

Infrared asphalt technology is an effective solution for critical repairs. This unique method blends hot-mix asphalt right in with the original and then compacts the area to create a seamless restoration. If you notice potholes–especially in high-traffic areas, pavement heaving or uneven surfaces surrounding catch basins (this is a common problem resulting after several freeze-thaw cycles), or rough surfaces in drive lanes or parking stalls, it is a good idea to consider infrared repair.

Infrared Benefits:
Infrared rays allow deep penetration asphalt repair and reclaiming without causing burning, scaling, or separation of the asphalt from the aggregate. Additional benefits include: cost savings, as the project is completed with fewer raw materials; time savings, as this repair option takes less time than traditional asphalt resurfacing; seamless repairs, as the patch bonds to existing surface and produces no joints for water to penetrate; and fewer traffic interruptions, as the patch can be driven on almost immediately.

Product Description:
The objective of this product is to prolong the life of existing asphalt pavements by use of infrared patching. This work will consist of furnishing all necessary materials, equipment and labor to perform the work as indicated on the contract proposal.

Materials:
Material will meet or exceed Colorado State Highway Specifications. Manufacturer certification is available upon request.

Service Preparation:
Area shall be swept clean prior to setting the unit. (Infrared will not penetrate dirt, ice, or water). Unit shall be placed so area of repair is at least 6″ inside edge of chamber frame and level using chain guide so it is 6″ to 9″ above the surface. If it is windy, metal shields will be placed against three sides. (This is not to trap heat but to block the wind and provide for an even surface.) Heating time for surface will vary from 6 to 12 minutes, depending upon temperature and weather conditions. After adequate heating of surface, unit shall be raised and moved forward sufficiently to allow for raking and treating of area to be repaired. Using the flat side of an asphalt lute, a picture frame will be made 6″ inside the perimeter, pushing the material in not out. Enough material will be removed to allow for the addition of a minimum of 1″ depth of new asphalt. reclamite rejuvenating agent will be sprayed evenly onto existing surface material.

Application:
Scarify area inside picture frame with asphalt lute. Enough material shall be added to allow for proper raking and compaction to grade. Care is taken not to leave excessive rock on the surface. Outside perimeter will be compacted as soon as possible to ensure thermal bonding. Final compaction will be completed in accordance with industry standards. Material in storage hopper will be new hot asphalt plant mix only. Material removed from repair area will be hauled away and returned to the plant for recycling.

Clean Up:
Any debris resulting from this process will be removed upon completion.
